- Don't assert: Derivation ATerms are not necessarily produced by Nix, and parsers should always throw graceful errors - Improve error message from `static void except(..)`, shows both what we expected and what we actually got. The intention is that we backport it, and then hopefully a few people might get slightly better errors if they try out new experimental drv files (for RFC 92) with an old version of Nix.
